Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 4, a detachable device for a stair template support frame base comprises a support base 1 and a support rod 2, wherein the support base 1 comprises a fixed cross rod 3 and a fixed vertical rod 4, one end of the fixed vertical rod 4 is fixedly connected with the middle part of the fixed cross rod 3, and a T-shaped structure is formed after connection.
The support base 1 is bound and fixed on the stair plates and the reinforcement meshes 13 of the rest platform, if the reinforcement distance is too large, the fixation is not firm, and a reinforcement can be added along the XY direction of the floor slab, so that the support base 1 is ensured to be safe and reliable.
The other end of the fixed vertical rod 4 is fixedly connected with a connecting sleeve 5; the lower end of the supporting rod 2 is in threaded connection with the connecting sleeve 5, and the upper part of the supporting rod 2 is fixedly connected with the supporting cross rod 6. When in support, the lower end of the support rod 2 is in threaded connection with the connecting sleeve 5, the vertical rod (the steel tube 12) of the template support frame is inserted into the support rod 2, and the lower end of the support rod 6 is contacted with the lower end of the steel tube 12 for support.
When the concrete 11 is received, the height of the top of the connecting sleeve 5 is consistent. After the floor slab concrete 11 reaches the design strength, dismantling the steel pipe 12; the support rod 2 is rotated, so that the support rod 2 is separated from the connecting sleeve 5, and the support rod 2 is dismounted. When the support rod 2 is removed, rust-proof paint can be smeared at the connecting sleeve 5 for rust-proof treatment.
Further, two support cross bars 6 are preferably arranged, the support rod 2 is positioned between the two support cross bars 6, and the middle parts of the two support cross bars 6 are fixedly connected with the upper parts of the support rods 2; specifically, a welding mode can be adopted.
Further, the connecting sleeve 5 is a cylinder or a prism, and a threaded hole is arranged in the middle of the connecting sleeve and is used for being connected with the supporting rod 2.
Further, the connecting sleeve 5 is a hexagonal prism, and when the concrete 11 reaches the related strength, the concrete 11 can limit the strength due to the hexagonal prism; so that the support bar 2 is prevented from being twisted when being rotationally removed.
Further, because the diameter difference between the support rod 2 and the steel pipe 12 is larger, after the steel pipe 12 is inserted into the support rod 2, a larger movable space exists between the support rod 2 and the steel pipe; the device further comprises a rubber block 7, the rubber block 7 is in sliding connection with the support rod 2, the lower end of the rubber block 7 is in contact with the support cross rod 6, and the rubber block 7 is supported through the support rod 2. After the steel pipe 12 is inserted, the rubber block 7 can extend into the steel pipe 12, namely, the rubber block can fill the gap between the rubber block and the steel pipe 12, and the movement of the steel pipe 12 is limited.
Further, the rubber block 7 is preferably conical in shape.
Further, after the steel pipe 12 is inserted, as the lower end of the rubber block 7 is provided with a circle of annular groove 8, the rubber block can deform after being extruded, and the situation that the steel pipe 12 is not concentric with the support rod 2 can be adapted.
Further, in order to prevent concrete 11 or other foreign matters from entering the threads of the connecting sleeve 5, thereby affecting the detachment of the support rod 2 in the later stage; the utility model also comprises a locking sleeve 9, wherein the locking sleeve 9 is connected with the lower end of the supporting rod 2 through threads; when the support rod 2 is connected with the connecting sleeve 5, the lower end of the locking sleeve 9 can be contacted with the upper surface of the connecting sleeve 5 by screwing the locking sleeve 9, so that the connection part of the connecting sleeve 5 and the support rod 2 is blocked, and foreign matters are prevented from entering. During disassembly, the supporting rod 2 can be directly rotated to be disassembled, or the locking sleeve 9 can be unscrewed first and then the supporting rod 2 can be rotated.
Further, for the convenience of rotation, a handle bar 10 is arranged on the locking sleeve 9; the handle bar 10 can be driven to rotate by being held by a hand.
The preferred embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model, and the various changes are included in the scope of the present utility model.
